“ For the darkness was total thus far, shapeless, without the ornament of stars; and the abyss gloomy; and the earth unfurnished; and the heaven unwrought: water [7] alone—always a perfect, gladsome, simple material substance, pure in itself—supplied a worthy vehicle to God. What of the fact that waters were in some way the regulating powers by which the disposition of the world thenceforward was constituted by God? For the suspension of the celestial firmament in the midst He caused by “dividing the waters;” [8] the suspension of “the dry land” He accomplished by “separating the waters.” ”
